When the material gains thermal energy it __________

• evaporates

• freezes

• condenses

• melts

which describes the behavior of the particles in a liquid?

• they vibrate and stay in their positions

• they glide past one another

• they spread out to fill the space

• they move very fast

when liquids lose thermal energy their particles ________

• slow down

• speed up

• go further

• come closer

gases don't have definite shape because_____________

• their particles are still

• there are large spaces between the particles

• the forces among the particles are very weak

• they colloid with each others

why do solids have shapes of their own?

• because their particles are strongly attached to each others

• because they vibrate

• because they have large spaces in between
